Styling tr id=bodyrow

I have the main content area ("bodyrow") removed from the header by using this css for one of the horizontal bars in the header:

height: 125px;
background: transparent !important;

In that 125px space is a graphic (code in the Header Image screen). Anyway, that's not important...

... what I'm trying to do is apply a box-shadow to tr id=bodyrow.

Is this possible? Nothing I have tried has worked. The drop shadow goes all the way up the page.

Thanks in advance for your time.
